Have you actually checked for power and ground? Do you have power at relay? Does relay energize?

No power to relay, only energizes with engine cranking

So none of the socket pins have 12v with key on?

No none.
I ran a jumper to the relay and pump started running.

Have you checked for a fuel pump fuse?

Have just about taken all of the wiring apart, haven't found a fuse as of yet

The fuse, if there is one would be in the fuse box.

No fuse for the fuel system in the fuse block.
Am now investigating the main relay.
Still no power to the computer and fuel relay

Looks like power originates at starter terminal. Maybe fusible link there?

Didn't find a fuseible link, only 2 wires at the starter.
Main relay is rusted really bad inside, as is the headlight relay.
